NAME

       sd_bus_interface_name_is_valid, sd_bus_service_name_is_valid, sd_bus_member_name_is_valid,
       sd_bus_object_path_is_valid - Check if a string is a valid bus name or object path

SYNOPSIS

       #include <systemd/sd-bus.h>

       int sd_bus_interface_name_is_valid(const char* p);

       int sd_bus_service_name_is_valid(const char* p);

       int sd_bus_member_name_is_valid(const char* p);

       int sd_bus_object_path_is_valid(const char* p);

DESCRIPTION

       sd_bus_interface_name_is_valid() checks if a given string p is a syntactically valid bus interface name.
       Similarly, sd_bus_service_name_is_valid() checks if the argument is a valid bus service name,
       sd_bus_member_name_is_valid() checks if the argument is a valid bus interface member name, and
       sd_bus_object_path_is_valid() checks if the argument is a valid bus object path. Those functions
       generally check that only allowed characters are used and that the length of the string is within limits.

RETURN VALUE

       Those functions return 1 if the argument is a valid interface / service / member name or object path, and
       0 if it is not. If the argument is NULL, an error is returned.

   Errors
       Returned errors may indicate the following problems:

       -EINVAL
           The p parameter is NULL.

           Added in version 246.

NOTES

       Functions described here are available as a shared library, which can be compiled against and linked to
       with the libsystemd pkg-config(1) file.

       The code described here uses getenv(3), which is declared to be not multi-thread-safe. This means that
       the code calling the functions described here must not call setenv(3) from a parallel thread. It is
       recommended to only do calls to setenv() from an early phase of the program when no other threads have
       been started.

HISTORY

       sd_bus_interface_name_is_valid(), sd_bus_service_name_is_valid(), sd_bus_member_name_is_valid(), and
       sd_bus_object_path_is_valid() were added in version 246.
